[PSUBS-MAILIST] Heads Question

[David Colombo via Personal_Submersibles]

Hi Alec,
I just spoke with the company that Roberto mentioned here in California to
place an order for dished head for the SeaQuestor. I will be using the
36"OD x .375 A516-70 steel what they call Elliptical 2:1 Ratio ASME Code
Type. It comes with a 2" flange which is really a 36" od ring shape as part
of the forming. This would mate up to the 36"OD first hull section. I'm
thinking that this would give me the best welding condition with two
matched surfaces that I would bevel for full pen welding. I'm curious why
not to have the flange?   My cost here is $480.00 + $96 to have it shipped
to northern California from southern California. even though its only a
nine hour drive one way, I think my time would be worth more than $5 hr to
pick it up. LOL Unless of course its cheaper in Canada (Hank), I might make
the trip and could serve as support crew for the Gamma. Any thoughts out
there from fellow Psubers would be appreciated.

Best Regards,
David Colombo
